SPECIFICATIQN forming part of Letters Patent No. 727,343, dated May 5, 1903.

Application filed March 2, 1903. Serial No. 145,692. (No model.)

W To all whom it may concern:

Be it known that I, EDWIN W. FULTON, a citizen of the United States, residing at Watertown, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Vises; and I do declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in vises; and it consistsin the provision of a jaw having a hollow cylindrical shank portion which is adapted to receive the solid shank portion of a movable jaw, the vise being mounted upon a suitable swiveled plate and means being provided for adjusting and holding the jaws at different angles to a perpendicular.

More specifically, the invention consists in a vise one jaw of which is provided with a hollow cylindrical shank portion adapted to receive a sliding jaw and in the provision of aheaded bolt having wings which are adapted to slide upon shoulders formed in the inner face of the cylindrical shank portion of the jaw, the shank portion of the bolt having a play in a segment-groove, whereby the two jaws, which are swivelly mounted, may be held at different angles to the axis of the jaws.

The invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the several views, in which- Figure 1 is a side elevation of my improved vise. Fig. 2 is a sectional view longitudinally through the vise and the swivel-plate supporting the same. Fig. 3 is a side elevation of one of the jaws, which isprovided with a hollow cylindrical shank portion. Fig. i is a perspective view of the swivel-plate, having its upper surface coneaved to receive the cylindrical shank portion of the jaw; and Fig. 5 is a detail view of the headed bolt.

Reference now being had to the details of the drawings by letter, A designates a portion of a bench to which my vise is applied,

and fastened to said bench by means of screws is a plate B, which is centrallyapertured to receive the shouldered portion 0 of the swivel-plate D. Said swivel-plate D, which is concaved on its upper face, has a portion thereof cut away, as at D, and has a central aperture d, which is in registration with an aperture a, formed in said bench. The shouldered portion upon the under face of the plate D is of such a diameter as to snugly fit in the aperture in the plate B and have swivel relation with said plate.

E designates one of the jaws of the vise, which has a hollow cylindrical shank portion E, which in the present instance has its inner wall substantially square in outline to receive the solid shank portion F of the sliding jaw F. An extensionfprojects from one end of the hollow cylindrical shank portion E and is provided as an additional support for the sliding jaw. Said cylindrical portion E has a curved segment-slot e extending substantially about one-half the circumference of said shank portion, and one end of said slot is laterally recessed, as at 6, providing means whereby the T-shaped head H of the bolt H may be inserted through the widened portion of said slot when applying the same to the shank portion for holding the parts together. The inner face of the shank portion E, adjacent to the slot therein, is cut away, forming a concaved shoulder K, and the wings N on the head of said bo1t,which are convexed on their under edges, are adapted to conform to and have a play upon the curved shoulders on the inner face of the shank portion E, adjacent to the edges of said slot. When the head of the bolt is thus positioned upon the shoulder of the shank portion E, the end of said head will be countersunken beneath the square outlined inner face of said shank portion and will not interfere or come in contact with the solid shankportion of the jaw F, thus allowing the vise to turn axially and to be held at different angles. 7 The cylindrical portion of the jaw E is adapted to rest in the concaved portion of the plate D and bearing therein substantially its whole length, and by reason of the shoulders 0, formed by cutting away one portion of the plate D, it will be observed that the jawE is allowed to make a one-half revolution, the movement of the jaw in opposite directions being limited by the edge of the jaw E coming in contact with the flat portion of the plate D, adjacent to the shouldered portion D. The shank portion of said bolt is adapted to be passed through the central aperture in the plate D and also in the hole a in the bench, and a washer R is preferably placed upon the bolt, after which a winged nut T is screwed upon the nut and against said washer, and by turning said nut the head of the bolt 'Will cause the cylindrical portion of the jaw E to bind with sufficient friction against the concaved surface of plate D to hold the same in an adjusted position.

From the foregoing it will be observed that by the provision of a vise embodying the features illustrated in my invention I am able, by making the shank portion of the jaw E cylindrical, to provide a substantial vise in which the entire cylindrical portion thereof will have abearing against the concaved plate and be securely held to the swivel-plate by the wings of the head of the bolt engaging the shoulders on the inner Wall of the vise, and when the nutis tightened the jaws will be held in adjusted positions axially, thus forming a strong vise which will bear heavy strain incident to its various uses.

I am aware that it is common in the art to construct Vises one of the jaws of which is provided with a hollow spherical shank portion having intersecting slots and adapted to produce a universal joint of the ball-andsocket type and provided with means for holding the spherical shank portion in different positions; but I make no claim for such construction.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. A vise comprising a jaw having a hollow cylindrical shank portion with a curved segment-slot transversely disposed, a sliding jaw carried by said cylindrical shankportion, the inner face of the cylindrical shank portion having a shoulder along the marginal edges of the slot therein, a headed bolt having wings at the end which are convexed and adapted to rest upon said shoulders along the marginal edges of the slot, a swivel-plate with its upper face concaved and adapted to conform to and form a seat for the cylindrical shank portion of said jaw, and means for frictionally holding the vise in different axial positions, as set forth.

2. A vise comprising a jaw having a hollow cylindrical shank portion with a transverse curved slot therein, one end of which opens into laterally-extending recesses,a slidingjaw carried by said shank portion, an extension upon the latter forming an additional support for the sliding jaw, a swivel-plate having its upper face concaved and adapted to conform to and form a seat for said cylindrical shank portion of the jaw, a portion of the swivelplate being cut away forming shoulders, a bolt having wings which are convexed and adapted to rest upon shoulders on the inner face of said cylindrical shank portion along the marginal edges of the slots therein, a fixed and apertured plate having a central aperture on which said swivelplate is seated, the threaded shank portion of said bolt adapted to pass through registering apertures in said plates and bench, and a nut adapted. to frictionally hold the vise' against the plate, as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

EDWIN W. FULTON.
